CIAT scientists working on the Great Lakes Bean Project in Rwanda have developed an interest in agroforestry - the production system where woody perennials are grown on the same land as agricultural crops. At present 40% of the beans produced in Rwanda are grown under banana plantations, and scientists working on the Bean Project are now investigating the interactions between the beans and trees. Two factors are under specific examination - the use of semi-climbing and climbing beans that may be more tolerant to competition for light than traditional bush beans, and the importance of banana planting density. A similar trial is also under way using Grevillea robusta as the tree component of the system. This species is widely grown in the region and is favoured because it fixes nitrogen and farmers appreciate its high production of firewood and green manure. Another area of research is the growing of stake-producing species that yield the stakes necessary to grow climbing beans. Three nitrogenfixing species are under test: Leucaena leucocephala, Calliandra calothyrsus and Sesbania sesban. Once the stakes have been grown, climbing beans will be introduced into the fields and grown alongside the stake-producing trees. Source: Bean newsletter.
